Application filed March 17, 1915, Serial No. 14,913.

To all whom it may concern:

Be-it known that I, ERNEST J. CRooKETT, a citizen of the United States,residing at Los Angeles', in the county of Los Angeles and State ofCalifornia, have invented a new and useful Receptacle, of which thefollowing is a specification.

An important object of this invention is the production of a new articleofmanufacture in the form of a receptacle for liquids and solids, saidreceptacle being manufactured of inexpensive material and being of greatstrength even though some of the material used in its manufacture is, initself, previous to its incorporation in the manu factured articleincapable of withstanding great strains.

' Another object is the production of a receptacle formed of stripmaterial, wound or arranged in such manner as to make the receptacle ofmaximum strength and minimum liability to leak.

Another object is to produce an article of this description havingsurfaces of maximum smoothness inside and outside.

()ther objects and advantages may appear from the subjoined detaildescription.

The accompanying drawings illustrate the invention.

Figure 1 is a perspective view of a receptacle constructed in accordancewith the provisions of this invention, some of the turns of the outerlayer being partly broken away layer.

Fig. 2 is a vertical mid section of Fig. 1.

The invention is not limited to the exact form of structure shown in thedrawings, it being understood that some features of the invention are ofimportance whether the article be termed a .tub, a barrel, or other.hollow body capable of being manufactured in accordance with thisinvention.

In the instance shown in thedrawings, the receptacle 1 is in the form ofa barrel or keg having two heads, one head forming a bottom 2 andtheother head formin a top 3. The top '3 may be solid or may e providedwith an opening 4. The receptacle 1 may be provided at its middle with abulge 5, as is usual in cooperage, to facilitate handling of thereceptacle when the same is filled with heavy material. 7

The peripheral wall of the receptacle 1 is to expose portions of thenext inner Specification of Letters Patent.

formed of any suitable number of stripsof overlapping strip materialwound in helical turns from end to end of the receptacle to form atubular body composed of superposed layers of any desired numberaccording to the strength of the receptacle desired and in accordancewith the character of-the material to be held by the receptacle. In theinstance shown, there are three such strips 6, 7, 8 lying side by sidewith abutting edges and there are five such layers, an inner layer a,intermediate layers 6, c, d, and an outer layer 6.

The helical turns in one of said layers diagonally cross the helicalturns in another of said layers, that is to say, the alternate layers a,c, and e have their helical turns wound aslant toward one endvof thereceptacle and the alternate layers 6, d have their helical turns woundaslant toward the opposite end of the receptacle.

The strips 6, 7 8 may be of fibrous mate rial such, for instance, aspaper of any suitable quality.

From the foregoing it is clear that the difierent layers are perfectlysmooth so that the inside and outside surfaces of the receptacle arequite smooth.

The strips may be of any suitable width and in practice I have usedstrips one inch in width, and have employed three separate continuousstrips wound together edge to edge to and fro from end to end of thereceptacle so that the turns in one layer will overlap the turns in thenext succeeding layer. The strips may be wound over a suitable form orcore, not shown, to facilitate manufacture of the article.

The winding of the strips so as to arrange them as above described maybe accomplished by any suitable mechanism such, for

instance, as the mechanism shown, described not ed with a suitablecompound The tubular body formed by the strips 6, 7, 8 is firmlyattached to the heads'2, 3 by suitable means, and in this instance forthis purpose the tubular'body extends outward beyond the heads to formannular tongues hereinbefore described and are wound in a spiral orspirals over the edge of said head and around the core to the oppositeend of said core to form the first or inner layer.

When the first layer is completed then the slant of the winding of thestrips is reversed so that the helix progresses toward the 'head to forma secondlayer and when said second layer is completed-then the directionof the progression of the helix is again reversed to form a third layer,and so on, the strips such as that being wound to and fro until thedesired number of layers have been formed.

The core is then removed or the hollow body thus produced is removedfrom the core, and the strips are cut to leave the annular tongue 9.Then the other head is placed in position and the rims 10 are fastenedin place over the receptacle.

What I claim is: A receptacle comprising a body' formed of superposedlayers of helical turns of strip material, the helical turns increasingin diameter from the ends of the body toward the middle portion of saidbody, the superposed layers extending beyond the outer face of the headto form an annular tongue,

and a rim provided with a groove to receive the tongues 9 to completethe annular tongue and fastened to the tongue and head.

In testimony whereof I have hereunto set my hand at Los Angeles,California, this 11th day of March, 1915.
